Modifies the config.mk to build secure images when building the SPL for secure devices.
Depending on the boot media, different images are needed for secure devices. The build generates u-boot*_HS_* files as appropriate for the different boot modes. The same u-boot binary file is processed slightly differently to produce a different boot image, depending on whether the user wants to boot off SPI, QSPI or other boot media.
Refer to README.ti-secure for more information.
